I have a bunch of incoming WETH
pairs that I am calling:
const reserves = await uPair.methods.getReserves().call()
My understanding is that getReserves()
will output the reserves based on the order the tokens of the pair are input to the function. However, I am wondering how that works when calling getReserves()
on a pair like I am doing above.
If I am getting token0
and token1
from the pair. Does that mean that token0
would match reserves0
. Then the same thing for token1
and reserves1
?
Lastly, I am getting outputs like the following:
Token0: 0x8E84f5B87F29c512c25026bF3169d134351c3Ba5
Token1: 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2
Pair: 0x8230F1f18FCB1Ca08BE63CFfe543F710a737f53A
Reserves 0: 399999999999999999999999
Reserves 1: 1000000000000000000
If my understanding is correct. Reserves1
would match token1
and that would mean that there is 1 ETH
for the WETH
side of the pairing and it looks like reserves are being returned in WEI
. What I do not understand is why are the decimals different between the two tokens? I am pretty new to this, but I would have thought that if it is a WETH
pairing they would be the same?
